PFlash offers 10x faster prefill for LLMs at 128K context

A new open-source project called PFlash has been developed to significantly speed up the prefill process for large language models running locally. This optimization is crucial because the initial delay before the first token appears is often more problematic than the generation speed itself. PFlash claims to be 10 times faster than llama.cpp for prefill operations, even when handling a context window of 128,000 tokens. AI
